The Bank for International Settlements (BIS) has revised the weights of the effective exchange rates (EERs) and has made other minor changes. Following these revisions, the figures have been retroactively revised.

The BIS calculates the weights of the EERs every three years after the corresponding period ends, using the three-year average of the total value of trade. As a result of the latest revision, the most recent weights have been updated to those for 2020-2022 from those for 2017-2019. For details, see the BIS website (Link to an external website).
